目的：由于丹麦位于北方，一年中一天的长度从7小时到17.5小时不等。实验和临床结果表明，近视的发展可能与环境光暴露有关。本研究的目的是调查丹麦近视儿童眼轴生长、近视进展或角膜屈光力变化是否随白天时间长短而变化。设计：横断面研究。参与者：235名8至14岁的儿童在临床试验筛选期间发现有近视（ClinicalTrial.gov标识符，NCT 00263471; 2005年12月6日访问）。所有发现有任何等效球镜值的儿童均为近视（
Objective: Because of the northern location of Denmark, the length of the day over the year varies from 7 to 17.5 hours. Experimental and clinical results suggest that the development of myopia may be related to ambient light exposure. The purpose of current study was to investigate whether axial eye growth, myopia progression, or corneal power change in Danish myopic children varies with the length of the day.Design: Cross-sectional study.Participants: Two hundred thirty-five children 8 to 14 years of age found to have myopia during screening for a clinical trial (ClinicalTrial.gov identifier, NCT00263471; accessed December 6, 2005). All children found to have any value of spherical equivalent that was myopic (
